[0001] 本申请是2003年10月17日提交的,申请号为02808563. 9,发明名称为《在无线分组数据服务连接中提供多重质量服务等级的方法和设备》的申请的分案申请。 [0001] This application is October 17, 2003 filed Application No. 02808563.9, entitled "to provide multiple levels of quality of service method and apparatus in a wireless packet data service connection" divisional application application.

[0002] 背景 [0002] BACKGROUND

[0003] 领域 [0003] field

[0004] 本发明涉及无线通信。 [0004] The present invention relates to wireless communications. 更具体地说,本发明涉及一种创新的在无线分组网络的移动站和无线网络之间提供多重质量服务等级的方法和设备。 More particularly, the present invention relates to an innovative method and apparatus for providing multiple quality of service levels in a wireless packet network between the mobile station and the radio network.

[0005] 背景 [0005] BACKGROUND

[0006] 使用码分多址(CDMA)调制技术是在具有大量系统用户的系统中便于通信的几种技术之一。 [0006] The use of code division multiple access (CDMA) modulation techniques is one of several techniques to facilitate communication in a system having a large number of system users. 其他的多重接入通信系统技术,例如时分多址(TDMA),频分多址(FDMA)和诸如单边带振幅压扩(ACSSB)之类的AM调制方案都是本领域内所熟知的。 Other multiple access communication system techniques, such as time division multiple access (TDMA), frequency division multiple access (FDMA) and amplitude companded single sideband as (ACSSB) AM modulation schemes such as are well known in the art. 这些技术已被标准化以便于不同公司生产的产品间的互操作。 These techniques have been standardized for interoperability between different company's products. 码分多址通信系统已在美国由无线通信工业联盟TIA/EIA/IS-95-B 进行标准化,题为“MOB ILESTATI ON-BASE STATION COMPATIBILITY STANDARD FOR DUAL-MODE WIDEBAND SPREADSPECTRUM CELLULAR SYSTEMS”(双模宽带扩展频谱蜂窝系统的移动站-基站兼容标准),此处称为IS-95。 CDMA communications systems have been standardized by the Telecommunications Industry Alliance wireless TIA / EIA / IS-95-B in the United States, titled "MOB ILESTATI ON-BASE STATION COMPATIBILITY STANDARD FOR DUAL-MODE WIDEBAND SPREADSPECTRUM CELLULAR SYSTEMS" (Dual-Mode Wideband Spread spectrum cellular system mobile station - base station compatibility standard), referred to herein as iS-95. 另外,一个新的CDMA通信系统的标准已在美国由无线通信工业联盟TIA提出,题为“Upper Layer (Layer3) Signaling Standard forcdma2000 Spread Spectrum Systems, Release A—Addendum 1,, (cdma2000 扩展频谱系统的上层(第3层)信号标准,版本A-附录1),发表于2000年10月27日,此处称为“cdma2000”。 In addition, a new standard CDMA communication systems has been proposed by the wireless communications industry consortium TIA in the United States, the upper entitled "Upper Layer (Layer3) Signaling Standard forcdma2000 Spread Spectrum Systems, Release A-Addendum 1 ,, (cdma2000 spread spectrum systems (layer 3) signal standard, version A- Appendix 1), published on October 27, 2000, referred to herein as "cdma2000".

[0007] 国际无线电联盟最近要求提交在无线通信信道上提供高速率数据和高质量语音服务的建议方法。 [0007] International Radio Union recently requested to provide advice for high speed data rates and high-quality voice services in a wireless communication channel. 第一个建议由无线通信工业联盟发表,题为“The IS-2000 ITU-RRTT Candidate Submission”(IS-2000 ITU-R RTT候选提交本)。 The first proposal published by the wireless communications industry consortium, entitled "The IS-2000 ITU-RRTT Candidate Submission" (IS-2000 ITU-R RTT candidate submission of this). 第二个建议由欧洲无线通信工业联盟(ETSI)发表,题为“The ETSI UMTS Terrestrial RadioAccess (UTRA) ITU-R RTT Candidate Submission"(ETSI UMTS 地面无线接入(UTRA)ITU-R RTT 候选提交本),也被称为“宽带CDMA”并以下称为“W-CDMA”。 The second proposal published by the European Radio Communications Industry Alliance (ETSI), entitled "The ETSI UMTS Terrestrial RadioAccess (UTRA) ITU-R RTT Candidate Submission" (ETSI UMTS Terrestrial Radio Access (UTRA) ITU-R RTT candidate submission of this ), also known as "wideband CDMA" and hereinafter referred to as "W-CDMA". 第三个建议由US TG 8/1提交,题为“The UffC-136 Candidate Submission”(UWC-136候选提交本),以下称为“EDGE”。 The third proposal presented by US TG 8/1, entitled "The UffC-136 Candidate Submission" (UWC-136 Candidate submission of this), hereinafter referred to as "EDGE". 这些提交本的内容都是公开的,并且是本领域内所熟知的。 Submit content are present disclosure, and are well known in the art.

[0008] IS-95起初是用来优化可变速率语音帧的传输的。 [0008] IS-95 was originally optimized for transmission of variable-rate voice frames. 后来的标准是建立在支持另外的包括分组数据服务的非语音服务的标准上。 Later, the standard is based on the standard supports other non-voice services, including packet data services. 一个这种分组数据服务在美国由无线通信工业联盟TIA/EIA/IS-707-A 标准化,题为“Data Service Options forSpread Spectrum Systems”(扩展频谱系统的数据服务选项),在此引用以供参考,并在以下称为“IS-707”。 Such a packet data service in the United States by the wireless communications industry consortium TIA / EIA / IS-707-A standardization, entitled "Data Service Options forSpread Spectrum Systems" (spread spectrum system data service option), incorporated herein by reference and hereinafter referred to as "IS-707".

[0009] IS-707描述了为通过IS-95无线网络发送Internet协议(IP)分组数据提供支持的技术。 [0009] IS-707 describes a support for sending Internet Protocol (IP) packet data IS-95 wireless network technology. 分组数据被用一个叫做点对点协议(PPP)的协议封装成无特征的字节流。 Data packet protocol used is called Point to Point Protocol (PPP) encapsulated into a featureless byte stream. 使用ppp, IP分组数据能在无线网络上以任意大小的片段来传输。 Use ppp, IP packet data can be of any size fragment of transmission over the wireless network. 无线网络在PPP协议会话期间保持PPP状态信息,或者在连续字节流在PPP结束点之间可能会作为长附加字节发送的时期。 PPP state information of the wireless network remains during the PPP session, or during a continuous stream of bytes may be sent as long additional bytes between the PPP end points. [0010] 这样一个字节流被进一步用一个叫做无线链路协议(RLP)的协议封装成一系列IS-95帧。 [0010] Such a byte stream protocol is further referred by a radio link protocol (RLP) is encapsulated into a series of IS-95 frames. RLP包括错误控制协议,使用否定回应(NAKs),接收器会提示发送器重发丢失的RLP帧。 RLP includes an error control protocol, using negative response (NAKs), the receiver will prompt transmitter retransmits the missing RLP frame. 因为RLP错误控制协议使用重发机制,RLP数据传输通常会在从发送器到接收器之间出现不同的传输时延。 Because the RLP error control protocol uses a retransmission mechanism, RLP data transmission generally different transmission delays will occur between from a transmitter to a receiver. 一种改进的RLP形式称为同步RLP (SRLP),发送器或接收器不会发送NAK,也不会重发,这是本领域内熟知的。 An improved form of RLP called Synchronous RLP (SRLP), a transmitter or receiver does not send NAK, a retransmission is not, which is well known in the art. SRLP中帧错误的概率比RLP中的要大,但是传输时延被保持在一个最小的恒量上。 SRLP the frame error probability is larger than the RLP, but the transmission delay is kept at a constant minimum.

[0011] 一个和可用于分组数据的无线移动站(MS)相连的远程网络节点诸如个人电脑或膝上电脑可按照IS-707标准通过无线网络接入到Internet。 [0011] and a mobile radio station (MS) can be used for the packet data network node connected to a remote computer such as a personal or laptop computer in accordance with IS-707 standard may access the Internet through a wireless network. 或者,一个诸如Web浏览器的远程网络节点可以被内置在MS中,可使PC更加随意。 Alternatively, a remote network node such as a Web browser can be built in MS, the PC can be more casual. 一个MS可以包括多个种类的设备, 但不仅限于PC卡、个人数据助理(PDA)、外部或内部调制解调器或者无线电话或终端。 MS may comprise a plurality of types of devices, but not limited to PC card, personal data assistants (PDA), external or internal modem, or wireless phone or terminal. MS 通过无线网络发送数据,由分组数据服务节点(PDSN)处理。 MS transmits data over a wireless network, the Packet Data Serving Node (PDSN) process. 典型的,PDSN维持MS和无线网络之间连接的PPP状态。 Typically, PDSN maintain the PPP state is connected between the MS and the wireless network. PDSN连接到一个诸如Internet的IP网络,并在无线网络和其他连接到该IP网络的实体或代理之间传输数据。 PDSN is connected to an IP network such as the Internet, and transmits data between the wireless network and the other connected to the IP network entities or agents. 这样,MS能通过无线数据连接向IP网络上的其他实体发送并接收数据。 Thus, MS is connected via a wireless data transmit and receive data to another entity on the IP network. IP网上的目标实质还称为顾客节点。 Essence target IP network also called client node. MS和PDSN之间的互动由EIA/TIA/IS-835 标准化,题为“WirelessIP Network Standard” (无线IP 网络标准), 发表于2000年6月,并在此称为“IS-835”。 The interaction between the MS and PDSN by the EIA / TIA / IS-835 standardization, entitled "WirelessIP Network Standard" (wireless IP network standard), published in June 2000, and referred to herein as "IS-835". 熟悉本领域的人员将会认识到,在一些网络中, PDSN会被互通函数(IWF)所取代。 Those skilled in the art will recognize that, in some networks, the PDSN is the interworking function (IWF) is replaced.

[0012] 为了提供更复杂的无线网络服务,就有一种设想和需要,通过同一个无线设备来同时提供不同种类的服务。 [0012] In order to provide a more complex wireless network services, there is a vision and the need to provide different kinds of services simultaneously through the same wireless device. 例如包括同时的语音和分组数据服务。 Including, for example, simultaneous voice and packet data services. 例如还包括多个种类的分组数据服务,比如同时的Web浏览和视频会议。 For example, also includes a plurality of types of packet data services, such as Web browsing and simultaneous video conference. 同时,技术的进步增加了无线设备和无线网络之间单个无线信道上可用的带宽。 Meanwhile, advances in technology increases the bandwidth between the wireless device and the wireless network is available on a single radio channel.

[0013] 然而,现在的网络还没有支持同时的具有实质性的不同等级的分组数据服务的能力。 [0013] Now, however, the network also did not support the ability to have a substantial grouping data from different levels of service at the same time. 例如,对时延敏感的应用比如视频会议和IP语音应用最好是在发送时不使用RLP重发, 以降低通过网络时分组数据时延的数量级和变化。 For example, for delay-sensitive applications such as video conferencing and voice over IP applications preferably do not use RLP retransmission when transmitting, to reduce the magnitude and variations of the packet data through the network delay. 另一方面,例如FTP,e-mail和Web浏览的应用对时延的敏感较低,所以最好在发送时使用RLP重发。 On the other hand, such as lower FTP, e-mail and Web browsing applications sensitive to delay, so it is best to use when sending RLP retransmission. 当应用要求不同等级的服务时,目前的无线标准适合于支持单个MS中要求几种等级的服务中的任何一种无线应用,但不是多重的应用。 When applications require different levels of service, current wireless standards suitable to support any kind of wireless applications in a single MS requires several levels of service, but not multiple applications. 于是,在该领域中就需要一种支持单个MS中使用不同等级的服务的多重应用的方法。 Thus, in the art a need for a method of application of a single multi-MS using different grades of service support.

[0014] 概述 [0014] Overview

[0015] 这里公开的实施例解决上面提出的需求,它使移动站(MS)和无线接入网络(RAN) 能在分配给该MS的单个IP地址上建立支持多重服务等级的连接。 [0015] Example embodiments disclosed herein address the needs set forth above, it enables the mobile station (MS) and the radio access network (RAN) supporting multiple connections can be established on a single class of service IP address assigned to the MS. 此处描述的实施例使数据发送器能使用单个IP地址来进行多种分组数据应用。 Embodiments described herein enable a data sender can use a single IP address for multiple packet data applications. 由每一个多重数据应用生成的分组数据被提供给单个点对点协议(PPP)栈和单个高等级数据链路控制(HDLC)组帧层来将分组数据转化成适合于通过无线链路协议(RLP)连接传输的字节流。 Each packet data is provided by a multiple data generated by an application to a single point to point protocol (PPP) stack and a single high-level data link control (HDLC) framing layer data into packets suitable for communicating over a radio link protocol (RLP) byte stream transport connection. 然后每一个得到的多重字节流被提供给具有不同的重发和时延属性的多重RLP连接中的一个。 Each multiple byte streams is then obtained is supplied to a multiple RLP having different retransmission and delay properties of the connection. 选择用来发送来自每一个应用的数据的RLP连接是基于最适合于该应用的服务等级。 RLP connection selected for sending data from each application is based on the best suited for the application service level.

[0016] 接收器在多重RLP连接上接收数据并将字节流重新组装成帧。 [0016] In the receiver the received data on the multiple RLP connections and the framing byte stream reassembly. 接收器可使用多重HDLC组帧层,一个HDLC组帧层对应于一个RLP连接。 The receiver may use multiple HDLC framing layers, one HDLC framing layer corresponding to a connection to the RLP. 或者,接收器可以使用单个HDLC组帧层和多个简单“解帧器”层。 Alternatively, the receiver may use a single HDLC framing layer and multiple simple "deframer" layers. 每一个解帧器层对应一个RLP连接,并搜索每个RLP字节流中为HDLC帧定界的标志特征。 Each deframer layer corresponds to one RLP connection, and searches for each RLP byte stream HDLC frame delimiting flags feature. 解帧器层不删除HDLC的转义编码,而是进一步向该单个HDLC 层以完整的、连续的HDLC帧的形式提供HDLC流数据。 Deframer layer does not remove HDLC escape coding, but further to the single HDLC layer provides HDLC stream data to complete HDLC frame of continuous form.

[0025] 细节描述 [0025] Details

[0026][功能定义部分] [0026] [Function definitions section]

[0027] 通过对每一个应用使用分开的点对点协议(PPP)栈,单个无线设备可以支持使用不同等级的服务的多重应用。 [0027] each application by using a separate Point to Point Protocol (PPP) stack, a single wireless device may support multiple applications use different grades of service. 这个方法具有几个缺点。 This method has several disadvantages. 在单个移动站(MS)上支持多重PPP 实例将不必要地消耗MS和分组数据服务节点(PDSN)上的大量数据内存。 Support multiple PPP on a single mobile station (MS) would needlessly consume large amounts instance data memory on the MS and Packet Data Serving Node (PDSN).

[0028] 另外,如果无线链路协议(RLP)会话已建立并被一个要求低时延的应用所使用, RLP应该被配置成不进行重发地操作。 [0028] Further, if the radio link protocol (RLP) session is established and low latency requirements of an application used, the RLP should be configured to operate without retransmissions. 这样就能具有低时延并能最好地适应于上述应用,但此时链路控制协议(LCP)和其他要求建立PPP链路的配置协议进行处理时将不具备错误控制。 This will have a low latency and can be best suited to the application, but this time when the Link Control Protocol (LCP) and other configuration protocol calls for the establishment of the PPP link processing will not have error control. 这将导致帧错误率的上升,而错误率的上升会在任何应用的分组数据能被发送之前就引起延迟甚至PPP配置的失败。 This will lead to increased frame error rate, error rate will rise to cause delays or even failure of PPP configuration before any packet data application can be sent.

[0029] 下面将要讨论的实施例通过在MS和无线网络之间的多重RLP实例上使用单个PPP 实例而克服了这些缺点。 Overcome these disadvantages using a single PPP instance Example Example [0029] As will be discussed by the MS and the wireless network between the multiple RLP. 图1显示了使用不同的并发服务等级的分组数据的发送器和接收器之间协议层的安排。 Figure 1 shows the arrangement of protocol layers between a sender and a receiver using different concurrent grades of service of packet data. 在一个示范实施例中,发送器维持两个无线链路协议(RLP)层(106 和108),一个高等级数据链路控制(HDLC)层104和一个点对点协议(PPP)层102。 In one exemplary embodiment, the sender maintains two Radio Link Protocol (RLP) layers (106 and 108), a high-level data link control (HDLC) layer 104 and a Point to Point Protocol (PPP) layer 102. 每一个RLP层实例使用不同等级的服务(106和108)。 Each RLP layer instances uses different grades of service (106 and 108). 比如,如果RLP1S106配置成根据接收器接收到的NAK帧来重新发送帧,RLP2sIOS就配置成没有重发。 For example, if configured RLP1S106 received NAK frame receiver according to re-transmission frame, RLP2sIOS will configured without retransmission. 换句话说,RLP1S106通过使用错误控制协议来提供更高的可靠性,RLP2sIOS提供不可靠的传输,但是具有固定的、最小的传输时延。 In other words, RLP1S106 by using an error control protocol provides greater reliability, RLP2sIOS provides unreliable transport, but with fixed, minimal transmission delay. 具有像RLP1S106这样特征的等级的服务这里简称为“可靠”。 With a level of service characteristics such as RLP1S106 here referred to as "reliable." 同样的,具有像RLP2sIOS 这样特征的服务等级这里称为“低时延”。 Also, with such features as RLP2sIOS level of service referred to herein as "low latency." 尽管这里描述的示范实施例只使用两种服务等级,使用更多数量的不同服务等级的实施方式也是可以预见的并且应当认为在这里所描述的实施例的范围之内。 While the exemplary embodiments described herein only uses two service level, a greater number of embodiments using different classes of service are also contemplated and should be considered within the scope of the embodiments described herein it. 比如,发送器和接收器可以各自使用附加的第三RLP层,提供一个可靠性介于“可靠”和“低时延”之间的中间服务等级。 For example, the transmitter and the receiver may each use an additional third RLP layer that provides an intermediate grade of service reliability interposed between "reliable" and "low latency."

[0030] 在一个示范实施例中,接收器也维持两个接收RLP实例(116和118)对应于发送器中相同的服务等级的RLP实例(106和108).例如1?^^106提供可靠的服务等级,1?1^11;116 就配置成可靠的服务等级。 [0030] In one exemplary embodiment, the receiver maintains two receive RLP instances (116 and 118) correspond to the same RLP instance class of service transmitter (106 and 108). For example 1? ^^ 106 provide a reliable service level, 11 ^ 11;? 116 configured to reliable service levels. 这样,当RLP1K116层检测到接收的RLP帧中序列号中断时,作为回应,RLPikI 16发送一个NAK帧来要求重发。 Thus, when the RLP frames RLP1K116 layer detects the sequence number of the received interrupt response, RLPikI 16 sends a NAK frame to request retransmission. 如果收到一个RLP NAK帧,RLP1S106就从它的重发缓冲区中重发所要求的帧。 If a received RLP NAK frame, RLP1S106 it from its retransmission buffer heavy frames required hair. 另一方面,如果RLP2sIOS配置成低时延的服务等级,则不管帧序列号中是否有中断,RLP2kIIS都不会发送NAK帧。 On the other hand, if RLP2sIOS configured to low-latency service level, regardless of whether there is an interrupt frame serial number, RLP2kIIS will not send a NAK frame. 实际上,RLP2sIOS和RLP2kIIS可能会完全忽略传输RLP帧的帧序列号以留出更多的空间给数据有效载荷。 Indeed, RLP2sIOS RLP2kIIS and may completely ignore the frame sequence number of the RLP frame transmitted to leave more room for data payload. 另外,RLP2sIOS不需要为先前发送的帧维持一个重发缓冲区,这样就节约了发送器中的内存。 Further, RLP2sIOS previously transmitted frames need not maintain a retransmission buffer, thus saving memory in the transmitter. 同样,RLP2kIIS不需要维持一个重新排序的缓存,这样就能节约接收器中的内存。 Similarly, RLP2kIIS no need to maintain a reordering buffer, which can save memory in the receiver.

[0031] 发送器中的PPPs层102将IP分组数据封装在PPP帧中。 [0031] PPPs layer 102 in the transmitter the data IP packet encapsulated in a PPP frame. 在一个示范实施例中, PPPs层102通过执行IP头部压缩,例如熟知的Van-Jacobsen(VJ)头部压缩来增加分组数据吞吐量。 In one exemplary embodiment, PPPs layer 102 by performing IP header compression such as the well-known Van-Jacobsen (VJ) header compression to increase packet data throughput. VJ头部压缩会导致某些头部信息的丢失,这些信息对于在多重RLP层(106和108)之间多路复用PPP分组数据是有用的。 VJ header compression can result in some loss of header information, information for multiple RLP layers in between (106 and 108) the multiplexed PPP packet data is useful. 在一个示范实施例中,PPPs层102将整个PPP 分组数据提供给HDLCs层104,并同时提供可用来确定使用哪个RLP层来发送数据帧的信息。 In one exemplary embodiment, the entire layer 102 PPPs PPP packet data to the HDLCs layer 104, and may be used to determine which also provides the RLP layer transmits data frames using the information. 在一个示范实施例中,PPPs层102为每一个提供给HDLCs层104的PPP分组数据提供一个服务等级标识符或者一个RLP实例标识符。 Providing a service level identifier in one exemplary embodiment, PPPs layer 102 is a PPP packet data is provided to each layer 104 HDLCs or a RLP instance identifier. HDLCs层104在PPP分组数据之间添加标示字符,并为接收自PPPs层102的每一个PPP分组数据添加一个循环冗余检验和(CRC)。 HDLCs layer 104 is added between the PPP packet is marked character data, and each PPP data packet and to add a cyclic redundancy check (CRC) is received from the layer 102 of PPPs. HDLCs层104还进行HDLC转义以保证标示字符或HDLC控制字符不会出现在单个帧的数据中。 HDLCs HDLC escape layer 104 is also to ensure that the designated characters or HDLC control characters do not appear in the data for a single frame. HDLCs层104典型地通过使用一个至少包括两个字符的转义序列来代替每一个标示字符或控制字符来实现HDLC转义。 HDLCs layer 104 is typically by use of an escape sequence comprising at least two characters of the label instead of each character or control character implement HDLC escape.

[0032] 图1中的接收器具有对每个RLP实例(116和118)各自分开的HDLC层(112和114)。 Receiver [0032] FIG 1 having each RLP instance (116 and 118) are each separate HDLC layer (112 and 114). 每个RLP实例(116和118)接收的RLP帧中的字节出现在对应的HDLC层实例(112 和114)中。 Each RLP instance (116 and 1 18) in the received RLP frame byte appears in the corresponding HDLC layer instances (112 and 114). 每个HDLC层实例(112和114)将转义序列分别放置在输入数据流中并将每个转义序列转化回传输的帧中的原始数据。 Each HDLC layer instance (112 and 114) in the escape sequence are placed in the input data stream and converts the transmission frame back into the original data of each escape sequence. HDLC层实例(112和114)还检验接帧中收到的CRC以确定接收的帧是否有通信错误。 HDLC layer instances (112 and 114) is also connected to frame check (CRC) to determine whether the received frame is received with a communication error. CRC不正确的帧被丢弃,具有正确CRC的帧被向上送到下一个协议层(PPPk) 110。 Incorrect CRC frames are discarded, with the correct CRC frame is sent to the next protocol layer up (PPPk) 110.

[0033] 图2显示了协议层的另一种安排。 [0033] Figure 2 shows another arrangement of protocol layers. 图2中发送器的协议层安排与图1中的发送器是一样的。 In the transmitter 12 in the transmitter arrangement of FIG protocol layer is the same as FIG. 然而,在接收器中,使用单个的HDLCk层212来代替为每一个RLP实例都对应一个HDLCk层。 However, in the receiver, using a single HDLCk layer 212 instead of each RLP instance corresponds to a HDLCk layer. 解帧器层(214和220)插入到RLP层(218和220)和HDLCk层212之间。 Deframer layers (214 and 220) are inserted into RLP layer (218 and 220) between the layer 212 and the HDLCk. 解帧器(214和220)的目的是保证只有完整的HDLC帧才被递送到HDLCk层212。 Objective deframer (214 and 220) is to ensure that only complete HDLC frame was only delivered to the HDLCk layer 212. 由于仅仅递送完整的HDLC帧,就不需要HDLCk层212区分,或重新组合多重HDLC帧中的数据。 Since only the delivery of a complete HDLC frame, there is no need to distinguish HDLCk layer 212, or recombined data of the multiple HDLC frames. 对于一个完整的帧,HDLCe层212删除转义序列并检验CRC。 For a complete frame, HDLCe layer 212 to delete the escape sequence and check CRC. 如果CRC被认为是正确的,HDLCe层212 就将PPP帧完全传输到PPPk层210。 If the CRC is considered correct, HDLCe PPP layer 212 will be fully transmitted to the frame 210 PPPk layer. 如果CRC不正确,HDLCe层212就丢弃错误的帧数据。 If the CRC is incorrect, HDLCe layer 212 discards the erroneous frame data.

[0034] 使用解帧器层(214和220)的一个好处是使接收器支持RLP (218和216)的多重实例而不对HDLCk层212的实施方式做任何改变。 [0034] One benefit of using deframer layers (214 and 220) is to support the receiver RLP (218 and 216) multiple instances without making any changes to the embodiment HDLCk layer 212. HDLCk层212甚至不需要知道接收到的字节是通过两个不同的RLP连接接收的。 HDLCk layer 212 need not even know that the received byte is received by the connection of two different RLP. 在将HDLCk层212和RLP协议层放置于不同的物理设备中的网络实施方式中,该实施方式的独立性特别重要。 In the HDLCk layer 212 and the RLP protocol layer is placed on a different physical device in the network embodiments, the independence of the embodiment is of particular importance. 比如,HDLCk层可能存在于标准的分组路由器中,而RLP层可能存在于无线网络中的无线接入网络(RAN)的分组数据控制函数(PCF)中。 For example, HDLCk layer may be present in a standard packet router, and the RLP layers might exist in the wireless network a radio access network (RAN) of a packet data control function (PCF) in. 使用解帧器层使支持多重RLP层和多重服务等级而不改变标准分组路由器的软件是可能的。 Use the de-framer support multiple RLP layer and multi-layer service level without changing the standard packet router software is possible.

[0035] 图3图示了一个支持上面讨论的多重服务等级的示例的移动站(MS)。 [0035] FIG. 3 illustrates an example of a multi-service support level discussed above mobile station (MS). 控制处理器302通过图示的无线调制解调器304、发射器306和天线308建立无线连接。 Control processor 302 illustrated by the wireless modem 304, transmitter 306 and antenna 308 to establish a wireless connection. 在一个示范实施例中,无线调制解调器304和发射器306按照cdma2000的说明来操作。 In one exemplary embodiment, the wireless modem 304 and transmitter 306 to operate in accordance with instructions cdma2000. 或者,无线调制解调器304和发射器306可以按照一些其他无线标准例如IS-95、W-CDMA或者EDGE来操作。 Alternatively, the wireless modem 304 and transmitter 306 may, for example, IS-95, W-CDMA, or EDGE to operate in accordance with other wireless standards.

[0036] 控制处理器302与存储器310相连,存储器310存有指示控制处理器302建立并使用如图1-2所示的协议层的代码和指令。 [0036] Control processor 302 is connected to a memory 310, a memory 310 stores a control processor 302 indicative of the code and instructions to establish and use the protocol layers shown in Fig 1-2. 存储器310可以包括RAM存储器、闪存、ROM存储器、EPROM存储器、EEPROM存储器、寄存器、硬盘、可移动磁盘、CD-ROM,或者其他任何存储媒体或本领域内所知的计算机可读媒体。 The memory 310 may include RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, CD-ROM, or any other storage medium or computer readable media known in the art.

[0037] 在一个示范实施例中,控制处理器302使用存储器310的一部分作为操作多重RLP 层所需的存储缓冲区(312和314)。 [0037] In one exemplary embodiment, a portion of the control processor 302 uses the memory 310 as required for operation of multiple storage buffer RLP layer (312 and 314). 比如,如果RLP1缓冲312对应于一个可靠的RLP连接, 它将包括一个为发送的RLP数据准备重发缓冲区和一个为接收的RLP数据准备的重排序缓冲区。 For example, if the RLP1 buffer 312 corresponds to a reliable RLP connection, it will include a retransmission buffer preparation and a reorder buffer for RLP data to prepare the received RLP data is transmitted. 如果RLP2缓冲314对应于一个低时延的RLP连接,则RLP2缓冲314既不需要重发缓冲区也不需要重排序缓冲区。 If the RLP2 buffer 314 corresponds to a low latency RLP connection, then the RLP2 buffer 314 does not require retransmission buffer does not need to reorder buffer. 因为这两个缓冲区是不需要的,RLP2缓冲314比RLP1缓冲312占用更少的存储器。 Because these two buffers are not needed, RLP2 buffer 314 than the RLP1 buffer 312 takes up less memory. 尽管被图示为不相连的,但是如果多重RLP实施方式中有些数据结构是公用的话,缓冲区(312和314)也可以是重叠的。 Although it illustrated as a not connected, but if multiple RLP some embodiments the data structure is common, then the buffer (312 and 314) may also be overlapped.

[0038] 图4图示了一个与分组网络例如Internet 416相连的示范无线通信网络。 [0038] FIG 4 illustrates an exemplary packet network and a wireless communication network connected to Internet 416, for example. 无线通信网络包括RAN 412和PDSN 414。 The wireless communication network includes a RAN 412 and PDSN 414. RAN 412进一步包括与一个或多个基站(没有画出) 相连的选择器402。 RAN 412 further includes a selector 402 with one or more base stations (not shown) is connected. RAN 412中的选择器402通常是基站控制器(BSC)的子系统,这里没有画出。 RAN 412 in the selector 402 is typically a base station controller (BSC) subsystem, not shown here. 发送到或接收自MS的所有无线数据将通过选择器来路由。 Sent to or received from the MS will be all wireless data routed through the selector. 作为对选择器402的补充,RAN 412还包括分组数据控制函数(PCF) 404。 As a complement to the selector 402, RAN 412 further includes a packet data control function (PCF) 404. 对于分组数据服务选项,选择器将接收来自MS的分组数据通过PCF 404发送,PCF 404进一步包括控制处理器460和存储器418。 For packet data service options, the selector receives the data packet transmitted from the MS through the PCF 404, PCF 404 further comprises a control processor 460 and a memory 418.

[0039] 存储器418包含有指示控制处理器460建立并使用如图1_2所示的协议层的代码和指令。 [0039] Memory 418 includes a control processor 460 indicative of the code and instructions to establish and use a protocol layer 1_2 as shown in FIG. 存储器418包括RAM存储器、闪存、ROM存储器、EPROM存储器、EEPROM存储器、寄存器、硬盘、可移动磁盘、CD-ROM,或者本领域内所知的其他任何形式的存储媒体或计算机可读媒体。 418 comprises any other form of RAM memory, flash memory, ROM memory, EPROM memory, EEPROM memory, registers, hard disk, a removable disk, CD-ROM, or memory known in the art of storage medium or computer readable media.

[0040] 在一个示范实施例中,控制处理器406在存储器418中建立多重缓冲区(408和410),这些缓冲区是用于为多个移动站建立的各种RLP连接的。 [0040] In one exemplary embodiment, the control processor 406 to establish multiple buffers (408 and 410) in the memory 418, these buffers are established for the various RLP is connected to a plurality of mobile stations. 在一个示范实施例中,RLP1 缓冲区408的池包括用于可靠RLP实例的重发和重排序缓冲区。 In one exemplary embodiment, RLP1 buffer pool 408 includes a reorder buffer and a retransmission reliable RLP instances. 另一个RLP2缓冲区410池用于低时延RLP实例,所以并不包括重发和重排序缓冲区。 Another pool of RLP2 buffers 410 used for low latency RLP instances, and therefore does not include a retransmission reorder buffer. 控制处理器406可以为单个MS 分配一个以上的RLP实例。 The control processor 406 may allocate more than one RLP instance to a single MS. 比如,一个RLP1缓冲区和一个RLP2缓冲区可以分配给运行一个组合的时延敏感和非时延敏感的应用的单个MS。 For example, one RLP1 buffer and one RLP2 buffer may be allocated delay-sensitive and non-delay-sensitive applications is to run a single MS combination.

[0041] 控制处理器406还与PDSN 414相连。 [0041] The control processor 406 is also connected to the PDSN 414. 在一个示范实施例中,当MS发送IP分组数据到分组网络416时,控制处理器406从选择器402接收RLP帧并使用相关的RLP缓冲区(408或410)来从RLP帧中提取出字节流。 In one exemplary embodiment, when the MS sends an IP packet to the packet data network 416, the control processor 406 to extract the RLP frames from the selector 402 receives the RLP frame using the associated RLP buffer (408 or 410) from the word throttle. 控制处理器406接下来发送这些字节到PDSN 414,PDSN 414按照HDLC协议从字节流中提取完整的IP分组数据(那些具有正确的CRC 值的)。 Control processor 406 sends the next byte to the PDSN 414, PDSN 414 extracts complete IP packet data from the byte stream in accordance with the HDLC protocol (those having correct CRC values). PDSN 414接下来将得到的IP分组数据传输到分组网络416。 IP packet data obtained PDSN 414 will next be transmitted to the packet network 416. 如果PDSN 414对单个MS,为多重RLP连接维持单个的HDLC连接,则控制处理器406在将字节从RLP帧发送到PDSN 414之前先进行解帧。 If the MS PDSN 414 for a single, multiple RLP connections to a single HDLC connection is maintained, the control processor 406 in the byte sent from the RLP frames to the PDSN 414 before the frame to be decompressed. 解帧的结果是将整个HDLC帧由控制处理器406传输到PDSN 414。 Results deframed whole HDLC frame is transmitted by the control processor 406 to the PDSN 414. 换句话说,控制处理器406保证了从一个RLP链路接收的HDLC帧中的数据不会和另一个RLP链路接收的HDLC帧中的数据相混合。 In other words, the control processor 406 ensures that the data from an HDLC frame received RLP data link and not another RLP link HDLC frame received mixed. 解帧将允许在能使用现存的PDSN的基础上更好地利用资源,现存的PDSN不能将多于一个PPP/HDLC分配给一个IP地址。 Solutions of the frame will allow better use of resources based on existing PDSN can be used on existing PDSN can not be more than a PPP / HDLC to an IP address assigned. [0042] 当分组网络416发送分组数据到MS时,分组数据首先被PDSN 414接收。 [0042] When a data packet network 416 transmits the packet to the MS, the packet data is first received PDSN 414. 在一个示范实施例中,PDSN 414将地址为该MS的IP数据报封装到一个PPP分组数据中并使用HDLC组帧来将得到的PPP帧转化为一个字节流。 In one exemplary embodiment, PDSN 414 for the MS address encapsulation of IP datagrams into a PPP data packet and PPP frame using HDLC framing to be obtained into a stream of bytes. 在一个示范实施例中,PDSN 414分配单个HDLC实例给单个MS,并使用该HDLC实例来对任何地址为定址到该MS的任何IP分组数据进行HDLC组帧。 In one exemplary embodiment, PDSN 414 to assign a single HDLC instance to a single MS, and uses that HDLC instance to be addressed to any IP data packet for the MS performs HDLC frames to any group address. 在一个可选实施例中,PDSN 414可以将多重HDLC实例分配给单个MSdi 得每一个HDLC实例对应一个与在该MS中的单个RLP连接。 In an alternative embodiment, PDSN 414 may be multiple HDLC instances assigned to a single MSdi each have a HDLC instance corresponds to a single RLP connection of the MS.

[0043] PDSN 414和网络416之间、PDSN 414和控制处理器406之间以及控制处理器406 和选择器402之间的连接可以使用包括以太网、Tl、ATM,或者其他光纤、有线或无线接口中的任何一种接口。 [0043] 416 between the connection between the control processor 402 PDSN 414 and 406 and between the control processor 406 and the selector may be used including Ethernet network and the PDSN 414, Tl, ATM, or other fiber, wired or wireless An interface to any interface. 在示范实施例中,控制处理器406和存储器418之间的连接通常为直接的硬件连接,比如存储器总线,但是也可以为上述讨论的其他种类的连接中的一个。 In the exemplary embodiment, control processor 406 and the memory 418 is generally connected between a direct hardware connection such as a memory bus, but may be a connection to other types of the above-discussed.

[0044] 图5是通过具有不同服务等级的多重RLP连接发送分组数据的一个示范方法的流程图。 [0044] FIG. 5 is a flowchart of an exemplary method for transmitting packet data through multiple RLP connections having different grades of service. 在一个示范实施例中,发送设备(图3中的302或图4中的406)的控制处理器使用图5所述的方法。 In one exemplary embodiment, the transmitting device (3302 in FIG. 4 or FIG. 406) of the control processor of FIG. 5 using the method of FIG. 在步骤502中,发送器把将要发送的IP分组数据封装到一个PPP分组中。 In step 502, IP packet data transmission to be transmitted is encapsulated into a PPP packet. 在一个示范实施例中,IP头部压缩比如Van-Jacobsen(VJ)头部压缩同样在步骤502中进行。 In one exemplary embodiment, IP header compression such as Van-Jacobsen (VJ) header compression in the same manner as in step 502. 在步骤504中,发送器接下来按照HDLC协议将PPP分组转化成字节流。 In step 504, the transmitter in accordance with the HDLC protocol to the next PPP packet is converted into a byte stream. 具体地说,每一个PPP分组转化成一个HDLC帧。 Specifically, each PPP packet is converted into an HDLC frame. 一个或多个标志字符被插入到字节流的HDLC帧之间, 每一个帧中出现的标志和控制字符被转义序列所取代。 One or more flag characters are inserted between HDLC frames in the byte stream, each frame appearing flag and control characters are replaced with escape sequences. 可能最普通的HDLC退出的例子是用两个八位位组0X7d0X5e (16进制)来取代标志序列八位位组0x7e (16进制)以及用两个八位位组0x7d0x5d (16进制)来取代八位位组0x7d (16进制)。 Perhaps the most common examples of HDLC exit is two octets 0X7d0X5e (16 hex) to replace the flag sequence octet 0x7e (16 hex) and two octets 0x7d0x5d (16 hex) replacing octet 0x7d (16 hex). 也在步骤504,为每一个帧计算一个CRC并插入到这个帧的尾部(指示该帧尾部的标示字符之前)。 Also in step 504, for each frame a CRC calculated and inserted at the tail of the frame (before the end of the frame designated character indicated). 在步骤506,发送器基于分组数据的种类来确定应该使用哪一组可用服务等级来发送帧数据。 In step 506, the transmitter determines a data frame to be transmitted using an available service level based on which set of data packet types. 如果要发送的IP分组数据使用非时延敏感应用诸如FTP或TCP,则在步骤508使用可靠RLP (具有重发和重排序)发送。 If the IP packet data to be transmitted using non-delay-sensitive applications such as FTP or TCP, then at step 508 using reliable RLP (with retransmission and re-ordering) transmission. 同样,任何不是IP分组的分组数据,但仍然是非时延敏感的(比如IPCP或LCP分组),也在步骤508使用可靠RLP发送。 Similarly, any data packet is not IP packets, but still non-delay-sensitive (such as IPCP or LCP packets) are sent in step 508 using reliable RLP. 时延敏感的类型的分组数据,比如用于视频相关服务的实时协议(RTP)分组数据,在步骤510使用低时延RLP发送。 Delay-sensitive packet data type, such as for video-related services in real-time protocol (RTP) packet data, using low latency RLP 510 transmits in step. 如上述所讨论的, 低时延RLP不发送或要求重发因为通信错误而丢失得RLP帧。 As discussed above, low latency RLP does not send or request retransmission of a communication error because the RLP frames have been lost. 尽管图5的示范实施例中显示了两种服务等级,熟悉本领域的人员应该能认识到其他系统可以使用多于两个的不同服务等级而不脱离本实施例所描述的范围。 Although in the exemplary embodiment of FIG. 5 shows two service level, a person skilled in the art should recognize that other systems may use more than two different classes of service without departing from the scope of the described embodiments. 比如,在步骤506,发送器可以通过一个具有中间可靠等级的RLP连接选择发送几种类型的分组数据。 For example, at step 506, the transmitter through an intermediate level of reliability RLP connection selected to transmit packet data having several types.

[0045] 图6是通过具有不同服务等级的RLP连接接收分组数据的一个示范方法的流程图。 [0045] FIG. 6 is a flowchart illustrating an exemplary method for connecting the data received by RLP packets with different levels of service. 在一个示范实施例中,接收设备(图3中的302或图4中的406)的控制处理器使用图6所示的方法。 In one exemplary embodiment, the receiving apparatus (406 in FIG. 4 or FIG. 3302) using the method of the control processor shown in Fig. 在步骤602,接收器处理通过一个或多个RLP连接接收的RLP帧。 In step 602, the receiver processes received connection through one or more RLP RLP frames. 在一个上述的示范实施例中,RLP帧通过两种类型的RLP连接,低时延连接和可靠连接接收。 In one embodiment the above-described exemplary embodiment, two types of RLP frames RLP connections, low latency and reliable connection connector receiver.

[0046] 如前面提到的IS-707所描述的,通过可靠RLP连接接收的RLP帧具有序列号,接收器使用该序列号来对帧和重发丢失的帧进行重排序。 [0046] The aforementioned IS-707 as described in connection received through a reliable RLP RLP frames having sequence number, the receiver uses the sequence number of the frame reordering and retransmission of the lost frame. 比如,如果一个序列号是“7”的RLP 帧由于通信错误而丢失,接收器发送一个NAK帧来要求重发那个帧。 For example, if a sequence number is "7" of the RLP frame is lost due to a communication error, the receiver sends a NAK frame to request retransmission of that frame. 当重发的帧收到时,在提供后续数据字节到HDLC层之前,使用该帧中所携带的数据来使数据字节流变得完整。 When the received frame to be retransmitted, providing subsequent data bytes to the HDLC layer before using the data in the frame so that the data carried in the byte stream to become full. 结果,从一个可靠RLP连接的RLP帧提取的数据字节流与发送器发送的帧比较通常没有间隙。 As a result, RLP frames from one frame to extract reliable RLP connection with the byte stream data transmitted from the transmitter are typically performed without a gap. 避免间隙的代价是数据具有可变的时延。 Gap costs avoid data having a variable delay. [0047] 相反,当低时延RLP链接上的一个RLP帧由于通信错误而丢失时,不会要求或进行重发。 [0047] In contrast, when an RLP frame on a low latency RLP link is lost due to a communication error, a retransmission request or not. 丢失的RLP帧中携带的任何数据字节会被出现在接收器HDLC层的数据字节流中而被忽略。 Any loss of data in the RLP frames are carried in bytes appear in the data stream receiver byte HDLC layer is ignored. 换句话说,在低时延RLP链路上丢失一个RLP帧总是会引起接收器上的和发送器发射的数据字节流之间的间隙。 In other words, a missing RLP frame on a low latency RLP link always causes a gap between the data bytes on the receiver and transmitter emitted. 然而,低时延RLP协议具有固定的小的时延,使它很适合于发送时延敏感类型的分组数据,比如RTP分组数据。 However, low latency RLP protocol has a fixed small delay, it is suitable for data packet transmission delay sensitive type, such as the RTP data packet.

[0048] 在图2所描述的示范实施例中,接收器使用通过多重RLP连接(图2中的116和118)接收的解帧器(图2中的214和220)来把完整的HDLC帧数据提供给单个HDLC协议层(图2中的212)。 [0048] embodiment, the receiver uses received through multiple RLP connections (116 and 118 in FIG. 2) deframer (214 in FIG. 2 and 220) in the exemplary embodiment as described with FIG be the complete HDLC frame data is supplied to a single HDLC protocol layer (212 in FIG. 2). 在图6中,解帧在步骤604中进行。 , Deframing performed in step 604 in FIG. 6. 在步骤606,HDLC协议层(图2中的212)删除由发送器插入的HDLC转义序列并检验每一个HDLC帧的CRC。 In step 606, HDLC protocol layer (212 in FIG. 2) inserted by a transmitter remove HDLC escape sequences and checks each HDLC frame CRC. 在步骤606,任何具有不正确CRC的HDLC帧被接收器删除。 In step 606, having an incorrect CRC any HDLC frame the receiver is removed. 得到的PPP帧接下来由HDLC协议层提供给PPP 层。 The resulting PPP frames by the PPP layer is provided next to the HDLC protocol layer. 在步骤608,PPP层对接收到的分组数据解封装,移去PPP头部和任何其他由发送器所做的改变。 In step 608, the data packet received PPP layer decapsulates the PPP header is removed, and any other changes made by the sender. 同样在步骤608,如果发送器对接收到的分组数据的IP头部进行了压缩(比如, 使用VJ头部压缩),则IP头部会扩展到它的原始尺寸和内容。 The same is compressed (for example, using VJ header compression) at step 608, if the sender of the received data packet docking IP header, the IP header will expand to its original size and contents. 在步骤610中,解封装的分组数据接下来进行路由。 In step 610, the next packet data routing the decapsulated. 尽管上面描述的实施例主要讨论了封装的IP分组数据,也可以使用PPP和HDLC来发送其他协议比如IPX或LCP的分组数据。 Although the embodiment described above discusses the encapsulated IP data packet, may be transmitted, such as IPX or LCP data packets of other protocols using PPP and HDLC.

[0049] 在一个使用解帧器(图2中的214和220)的示范实施例中,步骤602和604由RAN(图4中的412)中的控制处理器(图4中的406)进行,步骤606,608和610由PDSN(图4中的414)进行。 [0049] embodiment, step 602 and 604 by the (412 in FIG. 4), the RAN control processor (406 in FIG. 4) in an exemplary use a deframer (214 and 220 in FIG. 2) of the embodiment , steps 606, 608 and 610 by the PDSN (414 in FIG. 4). 在一个如图1所示的可选实施例中,PDSN(图4中的414)将多重HDLC 层(图1中112和114)分配给单个MS。 In an alternative embodiment shown in Figure 1, PDSN (414 in FIG. 4) will be assigned to a single MS multiple HDLC layers (112 and 114 in FIG. 1) embodiment shown in FIG. 在该实施例中,接收器不进行解帧,步骤604被忽略。 In this embodiment, the receiver does not remove the frames, step 604 is ignored. 在步骤602,每一个RLP层(图1中的116和118)将从接收的RLP帧中提取的数据直接提供给它对应的HDLC层(分别是图1中的112和114)。 In step 602, each RLP layer (116 and 118 in FIG. 1) from the received RLP frames extracted data directly to its corresponding HDLC layer (in FIG. 1, respectively 112 and 114).
